Task switching among windows on a graphical user interface. Responsive to user action (such as simultaneously pressing the ALT and TAB keys), a task selection window is displayed in which an iconic representation is provided for a plurality of windows, including at least one child window, and the iconic representations are arranged according to how recently the associated window had focus. Responsive to user action (such as pressing the TAB key while the ALT key remains depressed), a selection indicator moves through the selectable iconic representations in the order of the recency of the focus.
